I just got a Cloupor Hana mod clone from 101vape in the mail today. It works GREAT with my kayfuns at around 1 ohm +.. But anything below 8... barely even sizzles at all wattages and all resistances ive tried.. Is this a common problem? They said they'd replace it, but thats even more money ill need to spend to send it back to them and pay for the shipping back.
